The 1971 Chevrolet Vega had a problem before anyone drove it. The car was built around a single commercial ambition: it had to be cheap. GM's target was roughly a dollar a pound, and the base sedan came in at 2,249 pounds with an MSRP of $2,250 — close enough. But getting the Vega from the assembly plant in Lordstown, Ohio, to dealerships on the other side of the country was costing around $300 per car. On a $2,000 vehicle, that is not a rounding error. That is 15 percent of the purchase price before a single customer has turned a key.
The standard tri level autorack railcar of the era could carry 15 full sized cars. Because the Vega was a subcompact, three more could be squeezed in for a total of 18. The saving was marginal. The math still did not work.
So GM and Southern Pacific Railroad sat down and asked a different question: what if the cars did not have to lie flat?
Standing them on their noses
The answer was the Vert-A-Pac, a purpose built railcar that shipped Vegas nose down, standing vertically, loaded from both sides of the track. Within the same 89 foot footprint as a conventional tri level flatcar, the Vert-A-Pac held 30 cars instead of 18. According to Railway Age, that nearly doubled capacity reduced the transportation charge per vehicle by around 40 percent.
The side panels of the railcar were hinged at the bottom and folded down to form individual loading ramps, one for each car. A forklift closed them after loading, which locked the Vegas in position and sealed the entire cargo behind what were now solid walls. That last point mattered. Conventional autoracks were open to the elements. Brand new cars arrived at dealers having been rained on, hailed on, and occasionally targeted by thieves. The Vert-A-Pac, once closed, was essentially an enclosed car transporter on rails.

The engineering that made it possible
Tipping a car onto its nose and shipping it full of fluids across the country is not something you can do to an ordinary production vehicle. Chevrolet knew this early enough to design the Vega around it.
The Chevy Vega Wiki and Railway Age detail the specific modifications built into the production car. Engineers added a special oil baffle to the engine to stop oil from flooding the number one cylinder while vertical. Battery filler caps were repositioned to the high rear edge of the casing so acid could not spill during transport. The carburetor float bowl was fitted with a drain tube that routed fuel into the vapour canister during shipment rather than letting it pool. The windshield washer bottle was mounted at a 45 degree angle. Four removable cast steel sockets were built into the undercarriage of every Vega, allowing it to lock directly into the hooks on the railcar ramps. Plastic spacers were wedged in around the powertrain to protect the engine and transmission mounts, removed again once the car reached its destination.
The ambition was for each Vega to roll straight off the railcar and onto a dealer's lot, full of fuel and every other fluid, ready to drive. GM conducted vibration and low speed crash testing to ensure the vertically suspended cars would not shift or sustain damage during transit.
What it could not fix
The Vert-A-Pac was one of the more inventive logistics solutions in American automotive history. The Vega it was designed to carry was, by almost any measure, one of the worst cars Detroit produced in the 1970s. MotorTrend named it Car of the Year in 1971. Owners named it something else entirely, and not warmly. Rust, unreliability, and an aluminium engine that warped, leaked and wore out at alarming rates turned the Vega's reputation inside out within a few years of launch.
There is a mordant footnote in how vertical shipping may have contributed to the problem. Vehicle Nanny notes that Vegas sold close to the Lordstown plant — in Youngstown, Pittsburgh, and surrounding areas, shipped by conventional means — reportedly developed fewer front seal and gasket leaks than those transported by Vert-A-Pac. The engineering accommodations were real. Whether they were sufficient is another question.
When Chevrolet discontinued the Vega in 1977, the Vert-A-Pac went with it. The system had been designed specifically for the Vega and its corporate sibling, the Pontiac Astre. Nothing else in GM's lineup could use it. The racks were scrapped. The underlying flatcars were reassigned to other purposes.
Fifty years on, the Vert-A-Pac remains a genuinely clever piece of engineering attached to a genuinely troubled car. The shipping system worked. The vehicle it was built around is remembered rather differently.
